wbt_gaussian_scale_space: Gaussian scale space

Description

This tool uses the fast Gaussian approximation algorithm to produce scaled land-surface parameter measurements from an input DEM.

Usage

wbt_gaussian_scale_space(
  dem,
  output,
  output_zscore,
  output_scale,
  points = NULL,
  sigma = 0.5,
  step = 0.5,
  num_steps = 10,
  lsp = "Slope",
  z_factor = NULL,
  wd = NULL,
  verbose_mode = FALSE,
  compress_rasters = FALSE
)

Arguments

dem

Name of the input DEM raster file.

output

Name of the output land-surface parameter raster file.

output_zscore

Name of the output z-score raster file.

output_scale

Name of the output scale raster file.

points

Name of the input vector points shapefile.

sigma

Initial sigma value (cells).

step

Step size as any positive non-zero integer.

num_steps

Number of steps.

lsp

Output land-surface parameter; one of 'AnisotropyLTP', 'Aspect', 'DiffMeanElev', 'Eastness', 'Elevation', 'Hillshade', 'MeanCurvature', 'Northness', 'PlanCurvature', 'ProfileCurvature', 'Ruggedness', 'Slope', 'TanCurvature', 'TotalCurvature'.

z_factor

Optional multiplier for when the vertical and horizontal units are not the same.

wd

Changes the working directory.

verbose_mode

Sets verbose mode. If verbose mode is False, tools will not print output messages.

compress_rasters

Sets the flag used by WhiteboxTools to determine whether to use compression for output rasters.

Value

Returns the tool text outputs.
